To all whom it may concern:

Be it known that I, PLINY GATUoor, a citi zen of the United States, residing in the city of Newark, county of Essex, and, State of New Jersey, have invented certain new anduseful Improvements in Vertical- Spindle Bearings, of which the following is a specification.

My invention is more particularly adapted for use in connection with the driving spindles of talking machine motors, but from the nature of its structure, the bearing is capable of use in many other relations.

Hitherto it hasbeen the practice of motor manufacturers to provide a .simple aperture through the upper motor plate as a bearing for the turntable spindle, sometimes roviding an additional bushing of hardene metal in such aperture, but more often the metal of the plate itself is relied upon solely as the bearing surface. The difficulty with v liquid lubricant soon trickles down the spindle, leaving the bearing to run dry. 'When the motor is in fairly constant use, such a bearing requires constant attention 3.218% frequent lubrication to obtain the best -r ts.

The object of my invention, therefore is to provide an improved vertical spindle bearing of such a character as to' contain means within itself for retaining a supply of lubricant suflicient for the purpose and yet not add materially to the cost of the structure.

Improvement in sprin%lilnotors, in the last few years has been con ed to matters of detail and refinement, simplicity of structure and durability, as well asaccuracy and uniformityof speed, and my resent improvement is but one step in this ection. In carryin out m invention I rovide a structure su stantia y as illustrate 'in the accompanying drawings wherem- I Figure 1, is a side elevation, partly broken away, of a part of a motor frame, showing my improved spindle bearing. 1

Fig. 2, is a p an view of the same. Fig. 3, is a cross section on line 3-3 of in the direction of ta es set forth.

Similar reference numerals refer to like parts throughout the specification and draw- In the 'drawings'I have only shown so much of the motor plate ,or frame as will suflice to show the application of my improvement. g The frame'or plate 1 may be of cast iron or any suitable material and is with the vertical aperture 2, therein to receive the vertical 'drivin spindle 3. Integral with the frame, are t%e upper and lower bosses 4, and 5, as shown. The upper boss 4, is counterbored as at 6, to provide an enlarged recess 7, into WlllCl']. is fitted a felt washer 8, which is centrally apertured for the passage of the spindle 3. Fitted into this recess 7, and partially covering the washer 8, is the inverted cup shaped cap 9, which, when in place, serves to retain the felt washer in position, and prevent its displacement. The washer, in practice, is inserted into the ca. 9, which is then forced into the recess -7. iquid lubricant may then be applied to the felt, to the point of saturaprovided tion without fear of its following on down the spindle and leaving a dry bearing, since the felt washer serves as a reservoir to retain the lubricant, and supply it to the bearin just sufficient quantity at all times to a 0rd an eas running hearing.

In the mo ification shown in 'Fig. 4,'the,

upper plate 10, is of sheet metal provided with an enlarged opening 11, into which is fitted and secured the flanged bushing bearing 12. The other parts of the structure,

however are substantially the same as that hitherto described as for example, the upper and lower bosses 4, and 5, the aperture 2,

recess 7, felt washer 8, and cap 9.

It will thus be seen thatmy im 'roved bearing afiords an ample reservoir or lubricant and is provided with means for retaining it without material loss or escape for a long time, thereby removing two of the common drawbacks of the common spring motor-constant attention and frequent lubrication.

As above indicated, my improved bearing may be used wherever a vertical shaft is used without sacrificing any of the advanclaim 1. In a spindle bearing, the combination of a frame or plate having a counterbored,

apertured recess therein a lubricant retaining Washer fitted into the ceunterbored recess and a spindle in said aperture, and an inverted cup shaped cap frictionally secured in said counterloored recess for holding said Washer against displacement therefrom,

' 2. In a vertical spindle bearing, the combination of a vertically disposed spindle, an apertured support in which said spindle is naeaaee mounted, said support having a counterloored recess concentric with said spindle, and a lubricant retaining Washer fitted into said recess and surrounding said spindle, and an inverted cup shaped cap frictionally secured in said counterbored recess for holding said Washer against displacement therefrom PLINY CATUCCI.
